Answer:
Perimeter = 18.7 units
Area = 13.5 units²
Step-by-step explanation:
Perimeter of ADEC = AD + DE + EC + AC
Length of AD = 3 units
By applying Pythagoras theorem in ΔDBE,
DE² = DB² + BE²
DE² = 3² + 3²
DE = √18
DE = 4.24 units
Length of EC = 3 units
By applying Pythagoras theorem in ΔABC,
AC² = AB² + BC²
AC² = 6² + 6²
AC = √72
AC = 8.49 units
Perimeter of ADEC = 3 + 4.24 + 3 + 8.49
= 18.73 units
≈ 18.7 units
Area of ADEC = Area of ΔABC - Area of ΔBDE
Area of ΔABC = 
= 
= 18 units²
Area of ΔBDE = 
= 
= 4.5 units²
Area of ADEC = 18 - 4.5
= 13.5 units²
Answer:
Is a relation and a function.
Step-by-step explanation:
Every set of order pairs represent a relation.
Remember that a relation is a function when every element from the domain has a unique corresponding element in the range. In this case
f(-2) = 3
f(2) = 7
f(7) = -12
f(10) = -15
Therefore the relation is a function as well.
Well one pound is 2,000 lbs so do 2,000 / 25 = .175 of a ton!

To solve for y, you need to isolate/get the variable "y" by itself in the inequality:
x + 8y < 16 Subtract x on both sides
x - x + 8y < 16 - x
8y < 16 - x Divide 8 on both sides to get "y" by itself
